A new synthetic strategy for construction of the heptacyclic marine fungal alkaloid (±)-communesin F has been devised. Key reactions include an intramolecular Heck cyclization of a tetrasubstituted alkene to generate a tetracyclic enamide bearing one of the quaternary carbon centers (C7) of the alkaloid, an intramolecular reductive cyclization of an N-Boc aniline onto the oxindole moiety to form a
已经设计了一种用于构建七环海洋真菌生物碱 (±)-communesin F 的新合成策略。关键反应包括四取代烯烃的分子内 Heck 环化以生成带有生物碱季碳中心 (C7) 之一的四环烯酰胺,N- Boc 苯胺在羟吲哚部分上的分子内还原环化以形成五环骨架南氨基,立体选择性N - Boc-内酰胺烯醇化C-烯丙基化以引入第二季碳中心 (C8),叠氮化物还原/ N -Boc-内酰胺-开放级联通向北氨基。
Construction of Tricyclic Nitrogen Heterocycles by a Gold(I)‐Catalyzed Cascade Cyclization of Allenynes and Application to Polycyclic π‐Electron Systems
BrettPhosAuNTf2 in the presence of iPrOH to give 1,2-dihydrobenzo[cd]indole derivatives, some of which were converted into nitrogen-containing polycyclic aromatic compounds with highly conjugated π-electron systems. A hexacyclic indolium salt (see structure) showed concentration-dependent photophysical properties attributable to aggregate formation.

Gold(I)-Catalyzed Cascade Cyclization of Anilines with Diynes: Controllable Formation of Eight-Membered Ring-Fused Indoles and Propellane-Type Indolines
Heterocycle-fused indoles or indolines are distributed widely in a variety of natural products, bioactive agents, and pharmaceuticals. Herein, we describe the development of gold-catalyzed cascade reactions of anilines with diynes to form eight-membered ring-fused indoles and propellane-type indolines, both of which proceed through an intramolecular 5-endo-dig hydroamination followed by an 8-endo-dig
